Net Ionic Equation Calculator
Identify spectator ions and write the net ionic equation for common aqueous precipitation reactions.
Formula
Remove spectator ions (appear unchanged on both sides) from the complete ionic equation
- Spectator ions are dissolved ions that do not participate in the actual reaction.
- Net ionic equation shows only the species directly involved in the reaction.
- Solubility rules determine which salts precipitate (are insoluble).
AgNO₃ + NaCl
Inputs
- Select Reaction: agno3_nacl
Na⁺ and NO₃⁻ are spectators. Net: Ag⁺ + Cl⁻ → AgCl(s)
Frequently asked questions
What are spectator ions?
Ions that appear on both sides of the equation unchanged — they do not participate in the reaction.
How do I know which salt precipitates?
Use solubility rules. Most NO₃⁻, Na⁺, K⁺, NH₄⁺ salts are soluble. Most AgCl, BaSO₄, CaCO₃ are insoluble.
